How would you solve maths problems if you didn’t have a calculator or a computer For centuries, people in China have used an ancient counting tool to help solve such problems. The tool is called “abacus”. In Chinese, it is known as suanpan.
An abacus has a rectangular (长方形的) wooden frame. It is divided into the upper part and the lower part by a stick. A series of cross rods (棍子) extend from the top to the bottom of the frame (框架). Each rod has seven sliding beads (滑动的珠子), with two in the upper part and five in the lower part.
Each of the two beads in the upper part has a value of 5, while each of the beads in the lower part has a value of 1. Beginning at the right side of the abacus, the first rod represents (代表) ones. The second rod represents tens and the third represents hundreds. This pattern continues. A traditional abacus with 13 rods can represent very large numbers.
Besides counting, a Chinese abacus can also be used to do addition, subtraction, multiplication and division. It helped ancient Chinese people solve all kinds of maths problems they met in their daily life.
The Chinese abacus used to be the simplest calculating device for people in all trades in ancient China. A mathematician (数学家), Xu Yue at the end of the Eastern Han Dynasty first invented it. A famous mathematician, Cheng Dawei in the Ming Dynasty made it popular. To make people understand and use it easily, he also published a book called Suanfa Tong Zong. And this device has been equally famous to the "Four Great Inventions in Ancient China".
